DAPI Fluoromount-G is a water-soluble, 4',6-diamidino-2-phenylindole (DAPI) containing compound recommended for slides mounted after a staining procedure having an aqueous final step. When bound to DNA, DAPI fluoresces and is typically used as a nuclear/chromosomal counterstain. Since DAPI Fluoromount-G is water-soluble, the coverslip may be removed by submerging the slide in a PBS solution until the coverslip is loosened. This mounting medium also provides a semi-permanent seal for storage of slide preparations.
